Non auto's flowering on a 18hr light cycle??

Hi All,

I just noticed the first signs of my plants flowering, this is great but has also really confused me, as their still on a 18/6 light cycle. I'm growing 1x delahaze feminised, 1x cookies kush feminised and 3x unknown, under 2x 300w dual spectrum cfl's, in canna terra pro. They're 7-8 weeks old. The delahaze and cookies are definitely not auto but I can't say for certain on the 3 unknown.
The only nutrients I've been using so far is BioBizz Bio Grow.
I also have 1x gran daddy purp normal, which took much longer to germinate and also struggled a bit early on, so it's a good 3-4 weeks behind on growth.
So my question is should I continue on a 18/6 cycle or switch to 12/12? Ideally I wanted the purp to catch up a bit before I changed over but not at the expense of the entire crop.
Also what could of made them do this? They all look really healthy with no signs of stress and I haven't messed around their light cycle.

Thanks any help or advice is mucho appreciated)))

Mr Claus

does it look like an auto?

Have your light cycles been interupted? Could cause this or may have gotten wrong seeds and gotten autos.

I'm not entirely sure what auto's are supposed to look like?? (I haven't grown any before to the best of my knowledge). The seeds where bought from Herbies, so I don't think a mix up is possible but even then it's odd that all five plants (apart from the purp) have started to flower?? I've grown the 'unknown' for a few years now and it's never happened before...
The light cycle has been the exactly the same since they where potted, I'm quite thorough in regards to this.

thank you for your replies)))

Well if your on 18/6 and they are flowering you got an auto.
Photoperoids do not react that way or you have a light leak.

Agreed.Which seedbank did you buy from?

Hey guys))
Definitely no light leaks, my set up is in a walk in wardrobe in the spare room with mylar over the doors.
The cookies kush and grand daddy purp seeds where bought from herbie's pick and mix, the delahaze a free one from them.

The unknown seeds are from a load of bud I bought and as it was so nice I keep growing more)) (could well be auto's but I've grown them before and it's never happened).

But as it seems we've established they must be 'auto's' that's fine, the big question is do I change the light cycle now to 12/12? The little guy in the photo is the purp (the runt of the litter) and I'd ideally like him to grow a bit more before I change the light cycle.




thanks
